we get the the multiplication equations are 2 + 2 + 2 + 2 + 2 = 2 × 5, 5 + 5 + 5 + 5 + 5 = 5 × 5 and 4 groups of 3 = 3 × 4.
We are given some expressions and we need to find the multiplication equation for each one.
a) 2 + 2 + 2 + 2 + 2 will be
Since, 2 is repeating 5 times, we get that:
multiplication equation will be:
2 + 2 + 2 + 2 + 2 = 2 × 5
b) 5 + 5 + 5 + 5 + 5 will be
Since, 5 is repeating 5 times, we get that:
multiplication equation will be:
5 + 5 + 5 + 5 + 5 = 5 × 5
c ) 4 groups of 3 will be
Since, 3 is repeating 4 times, we get that:
multiplication equation will be:
4 groups of 3 = 3 × 4
Therefore, we get the the multiplication equations are 2 + 2 + 2 + 2 + 2 = 2 × 5, 5 + 5 + 5 + 5 + 5 = 5 × 5 and 4 groups of 3 = 3 × 4.

Using proportions, the coordinates of point C are given as follows:
C(0, -0.67).
What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
For this problem, the points are given as follows:
A(-4,-6), B(5,6), C(x,y).
The ratio of AC to CB is of 4:5, hence the following equation is constructed:
C - A = 4/9(B - A).
As the ratio of 4:5 means that the distance is 4/(4 + 5) = 4/9.
The x-coordinate of C is found applying the above equation as follows:
x + 4 = 4/9(5 + 4)
x + 4 = 4
x = 0.
The y-coordinate of C is also found applying the equation, as follows:
y + 6 = 4/9(6 + 6)
y + 6 = 5.33.
y = -0.67.
Hence the coordinates of point C are given as follows:
C(0, -0.67).

he cost in dollars of making x items is given by the function C(x) = 10x + 500.
a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.
b. What is the cost of making 25 items?
c. Suppose the maximum cost allowed is $1500. What are the domain and range of the cost function, C(x)?
Answers
We get the fixed cost as $ 150, cost of 25 items as $ 750, range as [0, 1500] and the domain as [0,150].
We are given the cost function:
C(x) = 10x + 500.
Fixed cost is when x = 0
C(0) = Fixed cost = 10 ( 0 ) + 500
Fixed cost = $ 500
Cost of making 25 products is x = 25
C(25) = 10 (25) + 500
C(25) = 250 + 500 = $ 750
Maximum cost allowed = $ 1500
Function becomes:
10x + 500 ≤ 1500
x + 50 ≤ 150
x ≤ 150 - 50
x ≤ 100
Range = [0, 1500]
Domain = [0, 150]
Therefore, we get the fixed cost as $ 150, cost of 25 items as $ 750, range as [0, 1500] and the domain as [0,150].

A local pizza shop has a membership program for frequent buyers. The membership costs $20 per month and members get a discounted price of $1.25 per slice of pizza. Chee purchased a membership to this pizza shop. How much would Chee have to pay the pizza shop if she bought 12 slices of pizza this month? What would be the monthly cost for x slices of pizza?
Answers
Answer:
$35 for 12 slices
Monthly cost for x slices of pizza = 20 + 1.25x
Step-by-step explanation:
Monthly Membership cost = $20
Discounted cost per slice of pizza = $1.25
Discounted total cost for 12 slices = $1.25 x 12 = $15
Total cost = 20 + 15 = $35 this momth
For x slices of pizza, monthly cost = 20 + 1.25x

Two angles are supplementary is the measure of one angle is 65.3 degrees what is the measure of the
other angle? Answer to the first decimal place, ie 79.5
Answers
The measure of the other angle is 114.7.
Given that the angles are supplementary,
Let the other angle be 'x'.
x + 65.3 = 180 degree
x = 114.7
hence, The other angle is 114.7 degrees.
The term "supplementary angles" refers to a pair of angles that always add up to 180°. These two perspectives are known as supplements. The term "supplementary" is derived from the Latin words "supply" and "plere," where "supply" means "supply" and "plere" means "fill." As a result, "supplementary" means "something that is supplied to complete a thing."
If two angles add up to 180 degrees, they are said to be supplementary angles. When supplementary angles are combined, they form a straight angle (180 degrees). In other words, if Angle 1 + Angle 2 = 180°, angles 1 and 2 are supplementary. Angles 1 and 2 are referred to as "supplements" in this case.

(a) f(0) = 1
(b) f(0) = 12

(a) A table of values;
x: -1, 0, 1, 2, 3
y: 7, 1, 6, -3, -4
Taking the function, f(x) = y, we have;
From the above values in the table, when x = 0, y = f(0) = 1
Therefore;
f(0) = 1(b) y = 12 - 2•x²
Taking the function, f(x) = y, we have;
At x = 0, y = f(0) = 12 - 2 × 0² = 12
Therefore;
f(0) = 12(c) A graph of a parabola passing through the points (-1, 3), (2, -6), (5, 3)

3 = a - b + c...(1)f(2) = -6 = a•(2)² + b•(2) + c = 4•a + 2•b + c

If there are about 7,000,000,000 people in the world and In Australia, there is a population of about 2.306 x [tex]10x^{7}[/tex] people, then the difference between the world's and Australia's populations is 697.694×[tex]10^{7}[/tex]
Given,
The total population of world = 7,000,000,000 peoples
Convert to suitable standard form
7,000,000,000 peoples = 700× [tex]10^{7}[/tex] peoples
The population of Australia = 2.306×[tex]10^{7}[/tex]
The difference = The population of world - The population of Australia

b) Boris can except to lose money. He can except to lose ___ dollars per draw.
c) Boris can except to break even( neither gain or lose money)
Answers
Boris can expect to break even ( neither gain or lose money) is the answer.
The probability of a number is calculated by dividing Favorable outcome by Total outcome.
The probability of a number between 1 to 10 = Favorable outcome/Total outcome
Favorable outcome =1 (any one number )
Total outcome = 10
Here p(x) is equal to 1 divided by 10
P(X)= 1/10= 0.1
The table gives us the Amount when we multiple X to P(X),
Expected value = (XiP(Xi))
When we substitute the value we get,
=(10.1)+(-50.1)+(30.1)+(-50.1)+(50.1)+(-50.1)+(70.1)+(-50.1)+(90.1)+(-50.1)
=0
So we will get zero after substituting the value.

the coordinate of X is at 8 units of P and at 4 units to the left of Q
So the coordinate of X is: -5 + 8 = 3
How to find the coordinates of point x?
We know that point X is between points P and Q, in such a way that the ratio between the lengths of the segments PX and XQ is 2:1
First, we can length of the segment PQ is equal to the difference between their coordinates, so we get:
L = 7 - (-5) = 12
Then the length of segment PQ is 12 units, if we divide that in 3 we will get:
12/3 = 4 units.
So the segment PQ can be divided into 3 segments of 4 units each.
If the ratio PX to XQ is 2:1
Then the segment PQ must be divided into 3 parts, such that PX takes two of these parts and XQ is the remaining one.
Then the coordinate of X is at 8 units of P and at 4 units to the left of Q
So the coordinate of X is: -5 + 8 = 3
